Sequential Backward Selection (SBS) google
The Sequential Backward Selection (SBS) algorithm is very similar to the Sequential Fortward Selection (SFS). The only difference is that we start with the complete feature set instead of the “null set” and remove features sequentially until we reach the number of desired features k. Note that features are never added back once they were removed, which (similar to SFS) is one of the biggest downsides of this algorithm. …

Proximity Measure google
In order to understand and act on situations that are represented by a set of objects, very often we are required to compare them. Humans perform this comparison subconsciously using the brain. In the context of artificial intelligence, however, we should be able to describe how the machine might perform this comparison. In this context, one of the basic elements that must be specified is the proximity measure between objects. …
